Tanthauzo la Chilema cha Splash: Splash mu kuwotcherera imatanthawuza madontho achitsulo osungunuka omwe amatulutsidwa mu dziwe losungunuka panthawi yowotcherera.Madontho awa amatha kugwa pamalo ozungulira ogwirira ntchito, kuchititsa roughness ndi kusagwirizana pamtunda, komanso kungayambitsenso kutayika kwa dziwe losungunuka, zomwe zimapangitsa mano, malo ophulika, ndi zolakwika zina pamtunda wowotcherera zomwe zimakhudza makina a weld. .
Kuwotcherera kumatanthawuza madontho achitsulo osungunuka omwe amatulutsidwa mu dziwe losungunuka panthawi yowotcherera.Madontho awa amatha kugwa pamalo ozungulira ogwirira ntchito, kuchititsa roughness ndi kusagwirizana pamtunda, komanso kungayambitsenso kutayika kwa dziwe losungunuka, zomwe zimapangitsa mano, malo ophulika, ndi zolakwika zina pamtunda wowotcherera zomwe zimakhudza makina a weld. .
Gulu la Splash:
Madontho ang'onoang'ono: Madontho ophatikizana omwe amapezeka m'mphepete mwa msoko wa weld komanso pamwamba pa zinthu, makamaka zomwe zimakhudza maonekedwe komanso osakhudzidwa ndi ntchito;Nthawi zambiri, malire osiyanitsa ndikuti dontholo limakhala lochepera 20% la m'lifupi mwa kuphatikizika kwa weld seam;
Large splatter: Pali kutayika kwabwino, kuwonetseredwa ngati madontho, malo ophulika, ma undercuts, etc. pamtunda wa weld seam, zomwe zingayambitse kupsinjika kosagwirizana ndi kupsinjika, zomwe zimakhudza magwiridwe antchito a weld seam.Cholinga chachikulu ndi pa mitundu iyi ya zolakwika.
Ndondomeko ya zochitika za Splash:
Splash amawonetseredwa ngati jekeseni wachitsulo chosungunuka mu dziwe losungunula m'njira yomwe ili pafupifupi perpendicular kwa kuwotcherera madzi pamwamba chifukwa cha mathamangitsidwe mkulu.Izi zitha kuwoneka bwino mu chithunzi chomwe chili pansipa, pomwe gawo lamadzimadzi limatuluka kuchokera pakuwotcherera kusungunuka ndikuwola kukhala madontho, ndikupanga ma splashes.
Chochitika cha Splash
Kuwotcherera kwa laser kumagawika kukhala matenthedwe matenthedwe komanso kuwotcherera kozama.
Kuwotcherera matenthedwe madutsidwe pafupifupi palibe zimachitika sipatsirana: Kutentha madutsidwe kuwotcherera makamaka kumafuna kulanda kutentha kuchokera pamwamba zinthu mpaka mkati, ndi pafupifupi sipatter kwaiye pa ndondomekoyi.Njirayi simaphatikizapo evaporation yachitsulo kapena kusintha kwazitsulo.
Kuwotcherera mwakuya ndiye chochitika chachikulu chomwe kuwotcherera kumapezeka: kuwotcherera mwakuya kumaphatikizapo kulowetsa laser molunjika ku zinthuzo, kusamutsa kutentha kuzinthuzo kudzera m'mabowo a keyholes, ndipo momwe zimachitikira zimakhala zokulirapo, zomwe zimapangitsa kuti pakhale chochitika chachikulu pomwe kuwotcherera kumachitika.
Monga momwe tawonera pamwambapa, akatswiri ena amagwiritsa ntchito kujambula kothamanga kwambiri kophatikizana ndi magalasi owoneka bwino kwambiri kuti awone momwe bowo la kiyiboli likuyendera panthawi yowotcherera ndi laser.Zitha kupezeka kuti laser imagunda kukhoma lakutsogolo kwa bowo la kiyi, ndikukankhira madziwo kuti aziyenda pansi, kudutsa bowo la kiyi ndikukafika kumchira wa dziwe losungunuka.Malo omwe laser amalandilidwa mkati mwa keyhole sanakhazikitsidwe, ndipo laser ili mu Fresnel mayamwidwe state mkati mwa keyhole.M'malo mwake, ndi chikhalidwe cha ma refractions angapo ndi kuyamwa, kusunga kukhalapo kwa madzi osungunuka a dziwe.Malo a laser refraction panthawi iliyonse amasintha ndi ngodya ya khoma la keyhole, zomwe zimapangitsa kuti chibowocho chikhale chopotoka.Malo a laser arradiation amasungunuka, amasanduka nthunzi, amakakamizidwa, ndikusintha, kotero kugwedezeka kwa peristaltic kumapita patsogolo.
Kuyerekezera kotchulidwa pamwambapa kumagwiritsa ntchito galasi lowoneka bwino lotentha kwambiri, lomwe kwenikweni ndi lofanana ndi mawonekedwe apakati a dziwe losungunuka.Ndipotu, kuyenda kwa dziwe losungunuka kumakhala kosiyana ndi momwe zinthu zilili zenizeni.Choncho, akatswiri ena agwiritsa ntchito zipangizo zamakono zozizira kwambiri.Panthawi yowotcherera, dziwe losungunuka limakhala lozizira kwambiri kuti lipeze nthawi yomweyo mkati mwa bowo la kiyi.Zitha kuwoneka bwino kuti laser ikugunda khoma lakutsogolo kwa bowo la kiyi, ndikupanga sitepe.Laser imachitapo kanthu pa sitepe iyi, kukankhira dziwe losungunuka kuti liziyenda pansi, ndikudzaza mpata wa makiyi panthawi yosunthira kutsogolo kwa laser, motero amapeza chithunzi chamayendedwe oyenda mkati mwa dziwe losungunuka la dziwe losungunuka.Monga momwe tawonetsera pachithunzi choyenera, kupanikizika kwachitsulo komwe kumapangidwa ndi laser ablation yazitsulo zamadzimadzi kumayendetsa dziwe losungunuka kuti lidutse khoma lakutsogolo.Bowo la kiyilo limalowera kumchira wa dziwe losungunuka, likukwera mmwamba ngati kasupe kuchokera kumbuyo ndikumakhudza pamwamba pa dziwe losungunuka.Panthawi imodzimodziyo, chifukwa cha kugwedezeka kwapamwamba (kutsika kwa kutentha kwapamwamba, kuwonjezereka kwakukulu), zitsulo zamadzimadzi mu dziwe losungunuka mchira zimakokedwa ndi kugwedezeka kwa pamwamba kuti zisunthire m'mphepete mwa dziwe losungunuka, kulimbitsa mosalekeza. .Chitsulo chamadzimadzi chomwe chitha kukhazikika m'tsogolomu chimazungulira kumbuyo mpaka kumchira wa bowo la keyhole, ndi zina zotero.
Chithunzi chojambula cha laser keyhole chozama kulowa mkati: A: Njira yowotcherera;B: Laser mtengo;C: Keyhole;D: Nthunzi yachitsulo, madzi a m'magazi;E: Gasi woteteza;F: Keyhole kutsogolo khoma (pre kusungunuka akupera);G: Kutuluka kopingasa kwa zinthu zosungunula kudzera pabowo la keyhole;H: Sungunulani dziwe kulimbitsa mawonekedwe;I: Njira yopita pansi ya dziwe losungunuka.
Njira yolumikizirana pakati pa laser ndi zinthu: Laser imagwira ntchito pamwamba pa zinthuzo, imatulutsa kutulutsa kwakukulu.Zinthuzo zimayamba kutenthedwa, kusungunuka, ndi kusanduka nthunzi.Pa nthawi ya nthunzi wa nthunzi, mpweya wachitsulo umayenda m'mwamba kuti dziwe losungunuka likhale lotsika kwambiri, zomwe zimapangitsa kuti pakhale bowo la kiyi.Laser imalowa m'bowo la keyhole ndipo imadutsa njira zingapo zotulutsa ndi kuyamwa, zomwe zimapangitsa kuti pakhale mpweya wochuluka wachitsulo wosunga fungulo;Laser makamaka imachita pakhoma lakutsogolo kwa bowo la kiyi, ndipo mpweya umapezeka makamaka pakhoma lakutsogolo la bowo la kiyi.Kuthamanga kwa recoil kumakankhira zitsulo zamadzimadzi kuchokera kukhoma lakutsogolo kwa bowo la kiyi kuti ziyende mozungulira bowo la kiyi kupita kumchira wa dziwe losungunuka.Madzi akuyenda mothamanga kwambiri kuzungulira bowo la kiyi amakhudza dziwe losungunuka mmwamba, kupanga mafunde okwera.Kenako, motsogozedwa ndi kugwedezeka kwapamtunda, imasunthira m'mphepete ndikukhazikika mozungulira motere.Splash makamaka imapezeka m'mphepete mwa bowo la kiyi, ndipo chitsulo chamadzi chakutsogolo chimadutsa mothamanga kwambiri ndikudutsa dziwe lakumbuyo lakumbuyo.
